It has to be
reminded, that document page 5 (not equal to the PDF numbering) is missing for
technical reason; as the XEROX electrostatic HT did fail at a critical moment.
This is often being caused by poor maintenance.

General:

Since the end of the European War a larger number of
German cable routes have been discovered that was not shown on the
internationally published list (Berne Lists) prior to the War.
